What is ‘tag’ RAM?

Tag RAM is used by the CPU and other hardware devices to keep account of exactly which memory address data is kept in the cache. Physically speaking, it is a bank of dedicated static RAM that is used to store addresses, which when matched by an input address, provides an output signal to perform a particular function.

The tag RAM’s size is what determines which range of main memory that is able to be cached and if more main RAM is added, then this extra capacity won’t be cached unless the tag RAM is also increased. This is only possible with some motherboards, as many don’t allow it.

The History of Microstar

Hailing from Taiwan, Microstar International (MSI) is a huge multinational corporation that designs and manufactures a range of IT hardware, as well as offering associated services. Their range includes desktop PCs, laptops, graphics cards, servers, and peripherals.

FoundingThe company was founded by five people back in 1986 and is listed on the stock exchange in Taiwan. Those people were Huang Jinqing, Lin Wentong, Lu Qilong, Hsu Xiang and Yu Xian’neng and each played their part in expanding their enterprise from its origins in Taipei City into the vast potential that existed in mainland China.

In the year 2000, Microstar set up a production plant in Shenzhen and then subsequently in 2001, an R&D facility in Kunshan in Eastern China.

Ex-Sony EmployeesEach one of the 5 founders were former employees of Japanese electronics giant, Sony and were made redundant in 1985 as part of a downsizing strategy. Without this change of direction, MSI might never have been in existence and their considerable industry experience and know-how would never have been thrown together.

Micro Star International was born in August 1986.

Company TimelineBy 1997, MSI had grown significantly and this led to a number of manufacturing plants being created across China over the next few years. Also during this time, MSI floated on the Stock Exchange in Taipei (otherwise known as the TAIEX).

Just 3 years later, in 2000, their global expansion gathered pace, as MSI opened its Netherlands based logistics centre, for the purpose of distribution across Europe.

Fast forward to 2008 and the company’s progress was still going strong, as it was widely viewed as being amongst the top, global Taiwanese brands. No mean feat when you consider that there were (and still are) over 500 such brands in existence in the country.

The upward trajectory for Microstar continued unabated and by 2013, MSI had been awarded as a key enterprise in the country by ‘Taiwan Excellence’ (Comprised of the Taiwan External Trade Development Council and the Taiwan Ministry of Economic Affairs) for a staggering 15 successive years.

Global LeaderJust two short years later, MSI was chosen as the fourth best brand of laptops by ‘Laptop magazine’ and it is now arguably the biggest single supplier of gaming laptops in the world, making it a trusted name in the field.

SponsorshipOver the last decade, the company has been involved in the sponsoring of professional eSports teams (like Digital Chaos and Fly Quest) and is even the primary benefactor to the international competition ‘MSI Beat IT’, which has been running since 2010.

If 4GB is installed then the system may only recognise 3.5GB or less. A 64-bit Operating System is required to utilise more than 4GB of memory.
